Leaf architectural studies in the asteraceae=I
ABSTRACT:
Leaf architectural studies have been made in 22 genera and 25 species belonging to 8 tribes of the asteraceae . leaves are oblong , ovate or elliptic . base acute , obtuse or lobate . apex acute , acuminate, attenuate or labate. Margin is lobed, wavy or serrate. Average size of the fully mature foliage leaves vary from species to species . major venation pattern conforms to pinnate- craspedodromous , pinnate- camptodromous with festooned brochidodromous secondaries , acrodromous and palinactinodromous types. Marginal ultimate venation is either incomplete , looped or fimbriate . number of primary veins vary according to the type of venation pattern. The number of secondaries on one side of the primary vary from species to species and

Influence of flurenol (morphactin) on yield, carbohydrates and post harvest changes in potato tubers
ABSTRACT:
Tuberization and yield of potato (solanum tubersoum L)cv. ‘ kufri alankar’ increased by single foliar spray of flurenol (n-butyl- 9-hydroxyfluorene-9-carboxylate) at 25 , 50 , 100 and 150 ppm but drastically reduced at 200 ppm. Carbohydrat contents in tubers increased at 25,50 and 100 ppm and decreased at 150 and 200 ppm of flurenol. Flurenol inhibited sprouting of the buds . loss in weight and rotting of tuber in storage were suppressed by flurenol . flurenol prevented conversion of starch into sugars and retarded the sweetening of tuber during storage.
